I tried to configure a device profile for 9971 with two DN lines, and I assigned it to an end user
which I logged in with into a Cisco IP phone 9971, the problem is that once I logged in, I'm finding only
the first DN line, the second is missing.
Knowing that I had the same problem with the 9951 model, I got no problem with 89XX models.
Can you, guys, give me some help regarding this issue?
I really appreciate your help, guys.
Try to create another Phone Button template dedicated for that UDP. Try also to add the same Phone button template to a physical phone 9971 and try to login there
